Hi, I am hoping someone here can help me identify if this is a malware/spyware issue. I am running Explorer 8 on a WinXP (SP3) machine. When I run IE8 there is additional iexplore.exe that starts up and I cannot close it (if I do, it just pops up again). This extra instance of iexplore.exe is the only one that runs regardless of how many IE8 windows I have up -- i.e. have 1 window up, Task Manager will show 2 instances of iexplore.exe, 6 windows up, Task Manager will show 7 instances of iexplore.exe. This extra instance of iexplore.exe does not run at startup and it does not run unless I startup IE8 first. It also seems to take up more memory than the IE8 windows that I startup myself. I have Avira Antivirus and have also run Kaspersky's online scan and Malwarebytes' Anti-Malware, none of them have spotted anything.

Does anyone have any idea why I keep getting this extra instance of iexplore.exe? I suspect it might be some 'legitimate' application that is causing the problem and that might be why none of the scans pick it up. But I have looked over everything running on this system and don't see anything odd. There are no IE8 add-ons except for the usual Flash, Java, Adobe Acrobat, no other toolbars or apps. Any input appreciated. Thank you.

** I came across a post on another website where a user notes that IE8 on WinXP will run an extra instance of iexplorer.exe, and eat up lots of memory, due to its crash recovery feature. I think this explains my issue. Admin feel free to delete this post or leave up since I assume others might notice this oddity with IE8 and run around frantically trying to scan for malware/virus/trojans.

That's my understanding too.

With the Automatic Crash Recovery feature, Internet Explorer8 will open a new process for the main window and another process with any opened tab. This feature allows Internet explorer to prevent itself from closing when a web site in one tab crashes. It has also been reported that this utilizes high memory resources.
